Thạc Sĩ Digital map of danang university of science and technology

Abstract
Digital map is not a new concept. It had been built in many personal, hand-held de-vices. It helps in improving living conditions and solving some life-issues. Developing the digital-map of DUT is necessary. Under our supervisor’s guidance, we have finished this project. Our aim is spreading the DUT’s reputation to people as more as possible.
This application still need a lot of works, but we’ve succeeded in building- up basic functions. This application is supported multi-platforms: Web, IOS and Android for better user experience.
1 Introduction
1.1 Background and Context
With the development of information technology, solving the daily problemshas be-come “digitalized”. It means that only with a computer or a smart-phone connected to the Internet, you can easily solve the problems quickly and accurately through one or more specific applications. “Digital Map” is one great app that allows users to view maps, locations, find the directions . It brings convenience to users in daily life and work. On today’s web, mapping solutions are a classic method. We use them to get the location of things, the orientation, and to do numerous other things. Most information have location, and if something has a location, it can be displayed on a map.
However, not anywhere gets a “Digital Map” for itself. And DUT is such a place. We found that, with the large campus of DUT, finding the halls, rooms in the campus isn’t easy for those new to the DUT, even for students who have followed 3 to 4 years in this university. The fact that many students, even graduated to the University of Tech-nology, didn’t know how many halls does the DUT have, how many floors of a hall, . Moreover, finding out information about the function, location, . the area, rooms in the school are also very limited. Therefore, we decided to build the Digital Map of DaNang University of Science and Technology Application for mobile platform and website platform.
1.2 Scope and Objectives
The problem posed is to build a map of the University of Technology with the follow-ing basic functions:
ã Show the map of DUT
ã Show the information of the halls: hall’s name, number of floor
ã Search the information
ã Find the location
ã Find the direction
We built this app on iOS, Android and the Web platform. This means that users who uses smartphones and PCs could easily access our application.
